Yes, they clinched the division in week 12 that year. On November 20th.
They also didn't go to the Super Bowl that year which is why I didn't list it.
1989 they clinched the division in the last week of the season if anyone was wondering.
It was very cold. Game time temp of 9 with 20+ mph wind.
You're close. 1993, week 17 v. the Jets. Cary Blanchard missed 3 FGs that day including one in the last minute, Bills won 16-14. Wasn't snowing that day though, but it was cold.
